Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.

  • Unter einer Zinkhütte, also einem Hüttenwerk für die Zinkerzeugung, versteht man einen Industriebetrieb zur Gewinnung von metallischem Zink. Die dafür genutzten Rohstoffe können sowohl Primärrohstoffe, also Erze, als auch Sekundärrohstoffe wie Recyclingmaterialien, zinkhaltige Abfälle, Schlacken etc. sein. Der Ausdruck Hütte umfasst dabei die Gesamtheit aller Maschinen, Einrichtungen, Apparate und Anlagen, einschließlich der Gebäude und des Grundstückes.In Deutschland erzeugt nur noch eine einzige Hütte, die Nordenhamer Zinkhütte GmbH in Nordenham, Zinkmetall aus Erzen.

  • La métallurgie extractive du zinc est l’ensemble des opérations permettant la fabrication de zinc métallique à partir du minerai, ou plus rarement à partir de déchets métallurgiques, d'aciéries notamment. Le minerai (généralement la blende) est préalablement traité par flottation afin de séparer, le sulfure de sa gangue (silicate, carbonate etc). On obtient un concentré de sulfure de zinc et de sulfure de plomb. Il existe alors deux voies de traitements : * la pyrométallurgique ; * l’hydrométallurgique suivi d’une opération d’électrométallurgie. (fr)
